CC2340R2: ISR callback and the handling of processor state

Tool/software:

This question is to confirm whether the CC2340R2 handles the store/restore of data when handling ISR. In this particular example, a GPIO is used to invoke an interrupt using the function GPIO_setCallback() . Should anything be added to the ISR code snippet below?

static void example_ISR(uint8_t LoopCounter)
{
    uint8_t level;
    if(LoopCounter == _ITERATIONS)
    {
        level = GPIO_read(_ITERATIONS);
        if (level == 0)
        {
            RLLTransport_PostEvt(RLL_MASTER_FLOW_ASSERT_SIG);   /* post event */
        }
        else
        {
             RLLTransport_PostEvt(RLL_MASTER_FLOW_CLEAR_SIG);   /* post event */
        }
    }
}   

Thank you!
